ABSTRACT:
To support speculative execution in a processor, a speculative look aside table stores information about deferred exceptions. Labels attached to predicates in the predicate register file of the processor serve as indices to a speculative look aside table. When an exception is generated for a speculative operation, the speculative look aside table is updated. Deferred exceptions are detected and handled when the processor reads the corresponding entry in the speculative look aside table during an explicit or implicit check operation.
